Evaluate two sorting or two search algorithms : Bisection search - recursive implementation

The video tutorial explains the recursive implementation of a bisection search algorithm, highlighting differences from the iterative approach. It covers the base case, recursive conditions, and logic for recursive calls. The tutorial compares recursive and iterative methods, emphasizing the advantages of recursion, such as maintaining index tracking without copying arrays. The video concludes with testing the recursive function, demonstrating its effectiveness in finding values within a list.

What is a key difference between the recursive and iterative implementations of bisection search?

• Iterative implementation uses recursion.

• Recursive implementation includes start and stop parameters.

• Iterative implementation requires start and stop parameters.

• Recursive implementation uses a while loop.

When does the recursive function return 'item not found'?

• When the start index is less than the stop index.

• When the start index is zero.

• When the start index is equal to the stop index.

• When the start index is greater than the stop index.

How is the mid index calculated in the recursive bisection search?

• By adding start and stop.

• By multiplying start and stop.

• By subtracting start from stop and dividing by two.

• By adding start and stop and dividing by two.

What happens if the item is greater than the mid index value during the search?

• The search stops immediately.

• The search continues to the right of the list.

• The search restarts from the beginning.

• The search continues to the left of the list.

In the recursive approach, what is the advantage of not using array slices?

• It reduces the number of recursive calls.

• It allows tracking of the original index.

• It simplifies the code.

• It increases the speed of execution.

Why is it important to track the index in the original list?

• To increase the recursion depth.

• To reduce the number of comparisons.

• To find the exact position of the item.

• To ensure the list is sorted.

What would be unnecessary if the function only needed to return whether an item was found?

• The start and stop parameters.

• The mid index calculation.

• The recursive function calls.

• The original array reference.
